Hypocrite

(3 syl.). Prince of hypocrites. Tiberius Caesar was so
called, because he affected a great regard for decency, but indulged in
the most detestable lust and cruelty (B.C. 42, 14 to A.D. 37).
Abdallah Ibn Obba and his partisans were called The Hypocrites
by Mahomet, because they feigned to be friends, but were in reality
disguised foes.
